From abstract: The results of diamond-drill exploration for the Shinarump member of the Chinle formation in Clay Gulch, San Juan County, Utah, indicate that between Clay Gulch and exposures along Red House Cliffs, about 2 miles east, a dominantly continuous blanket of the Shinarump member wedges out northeast of a line trending N. 150 W.

Abstract: "Some discussion is given of the possible real and charge parity degeneracies of K mesons. An explicit model is used to illustrate the superselection rule, which forbids the K meson to be a mixture of intrinsic parity states and at the same time conserve parity in decay. The discussion is extended to charge parity; the 01, 02 scheme appears to be more than an exercise in polarization phenomenons and to involve a radically new basic assumption--namely, that the 0-0 and 0-(-0) are degenerate states. The [tau]-0 is compared with the 02 as a long-lived K meson, and a method of experimental distinction is described."

Abstract: And investigation of the interactions between 300-Mev neutrons and xenon was made by means of a cloud chamber in a pulsed magnetic field of 21,700 gauss placed in the neutron beam of the 184-inch Berkeley cyclotron. Eighty-seven negative pion events and 257 other stars were analyzed. In addition an experimental check was made on the energy of the incoming neutrons. Classification, identification, and angular and energy distributions of prongs associated with all events are presented. Interpretations of results are given.

The following report discusses a method used to solve a two-end-point problem for second-order differential equations. The point of the method is to keep the two-end-points in the same order of magnitude.

Report discussing the properties of a plasma held in a steady state by a magnetic field. Properties such as "electric and magnetic fields, current density, particle density, and macroscopic velocity" are determined analytically by assuming uniform temperature throughout the plasma.

This report follows experiments concerned with a particular proposal or set of related proposals of means for the production of plasma with density above 10-11 particles per cm-3 with a temperature of the order of a few electron volts.

Report discussing a plasma containment configuration which appears to have no escape cone. From abstract: "Arguments are given to show how the containment process works, including experimental evidence deduced from published reports on "electromagnetic levitation."

Summary: By controlling certain elements within a vacuum chamber from an external station, a charged particle experiment is performed without opening the chamber, thereby saving considerable time and labor. By pre-programming the experimental sequence on the external controls, the experiment can be performed from beginning to end with a minimum of operator attention. The data collected can be read out automatically on a punched paper tape for subsequent transmission to a digital computer.

This report provides a review of the design and performance of the embankment and foundation of Blakely Mountain Dam in Arkansas. "This study is one of a series of similar studies of the foundation and soil mechanics features of earth dams [...] In these studies field experience is analyzed and performance of the completed structures is compared with design predictions to provide information for use in the design and construction of future projects" (p. 1).

Memorandum presenting force and moment characteristics of configurations employing wings of very low aspect ratio as determined for Mach numbers of 1.97 and 3.33. The angle of attack range was from 0 to 17 degrees for Mach number 1.97 and from 0 to 30 degrees for Mach number 3.33. Results regarding experimental force and moment characteristics, comparisons of theoretical and experimental force and moment characteristics, and visual observations of flow over models are provided.

Report discussing testing to determine the static lateral and directional stability and control characteristics of a model of the Republic F-105 airplane. The effects of various vertical tails and ventral fins, wing-tip fences, a canopy fin, fuselage nose shape, external stores, and deflection of horizontal tail, spoiler, and rudder were explored.

Memorandum presenting a review of the subsonic-diffuser data available in the literature, which is then reduced to certain appropriate performance coefficients and presented as functions of the significant geometric and flow variables. Results regarding total-pressure-loss factor, diffuser effectiveness, recovery of diffuser effectiveness in the tailpipe, inlet speed effects, exit flow distributions, boundary-layer control, and effects of distorted inlet velocity distribution are provided.

Report issued by the Bureau of Mines over investigations of coking coal reserves of Hamilton County, Tennessee. Testing to determine suitability for producing metallurgical coke is also presented. This report includes tables, maps, and illustrations.

Report issued by the Bureau of Mines over investigations of coking-coal reserves of Marion County, West Virginia. Methods used, and measurements of coal reserves are listed. This report includes tables, and maps.

Report presenting an investigation of spontaneous ignition temperatures from 1 to 9 atmospheres in the air for n-heptane, isooctane, benzene, JP-4, and JP-5 fuels. Time lags before ignition were measured at each pressure for all fuels. Results regarding the effect of pressure, general comparisons of all fuels, and ignition-lag experiments are provided.

"The results of an experimental investigation of the strength of multiweb beams with corrugated webs are reported. Included in the investigation were two types of connection between the web and the skin. A comparison between the structural efficiency of corrugated-web and channel-web multiweb beams is presented, and it is shown that, for a considerable range of the structural index, corrugated-web beams can be built which are structurally more efficient than channel-web beams" (p. 1).

Report presenting mass-flow tables for ratios of specific heats for the entire range of critical velocity ratio. The tables enable a quick and accurate determination of the integrated average specific mass flow across a region where the end-point velocities are known. A numerical example using the tables is also provided.

Report presenting an application of airfoil design methods to a series of related turbine-blade profiles to satisfy the conditions of inlet flow angle and turning angle encountered in the usual range of turbine operation. Satisfactory flow conditions were obtained in all of the blade passages tested. Results regarding the turning angles, wake losses, surface pressure distributions, critical Mach numbers, application of compressibility corrections to low-speed tests, and selection of design camber are provided.

Note presenting a description of a new class of frequency-selective shock absorbers called band-pass shock absorbers, which were conceived as a means of overcoming some of the limitations of conventional shock absorbers. The shock absorbers may be designed to isolate two bodies from each other over certain ranges of exciting frequencies or rates of load application while coupling them over the remainder of the frequency spectrum.

The interaction of bearing and tensile loads on the creep behavior of joints was studied. A specimen was designed for this study which possessed some of the general features of pin and rivet joint connections and an apparatus was constructed to apply both bearing and tensile loads to the joint model. Deformation measurements were made by use of a photogrid printed on the joint model.

Report presenting an investigation in the low-turbulence pressure tunnel to determine the effect of size and location of a sandpaper type of roughness on the Reynolds number for transition. Transition was observed by means of a hot-wire anemometer at various chordwise stations for each position of roughness.

A simple method for calculating the characteristics of the Dutch roll motion of an airplane is obtained by arranging the lateral equations of motion in such form and order that an iterative process is quickly convergent. Primary effects of variation of the important stability derivatives on the period and damping can be seen more clearly from the iterative method than from the fourth-order characteristic equation.

Report presenting an experimental determination of radiation and recovery corrections and time constraints for several designs of shielded and unshielded thermocouple probes using chromel-alumel wire. Radiation and time constant data were obtained for Mach numbers from 0.3 to 0.9 and a range of static pressures and temperatures. Tables and graphs are presented which show the correction factors of the various designs to aid in selecting a probe for a particular application.
